Embodiment Construction

[0030] Firstly, taking magnetron sputtering metallized copper film on the surface of inorganic hollow microspheres as a preferred embodiment, the process steps are described in detail as follows:

[0031] (1) Prepare the hollow microsphere particles;

[0032] (2) Open the vacuum chamber and place the metal copper or one of silver, aluminum, cobalt and nickel sputtering target on the sputtering target holder;

[0033] (3) install the sample dish loaded with hollow microbeads on the sample stage;

[0034] (4) Close the vacuum chamber, turn on the mechanical pump to evacuate to 1Pa~10Pa;

[0035] (5) Turn on the molecular pump to evacuate to 1.0×10 -3 Pa~8.0×10 -3 Pa;

[0036] (6) Turn on the flowmeter and fill the vacuum chamber with argon to 0.1Pa~10Pa;

[0037] (7) Turn on the ultrasonic vibrator or mechanical vibrator and the sample rack swing device, adjust the ultrasonic vibration power range: 10w ~ 200w, or the mechanical vibration power range: 5w ~ 5000w, the sample ...

Description

technical field [0001] The invention relates to a vacuum coating process and equipment thereof, in particular to a vacuum coating metal film process and equipment on the surface of microparticles. Background technique [0002] At present, compared with the bulk of the same material, the physical and chemical properties of microparticles have changed significantly, and they have excellent optical, electrical, magnetic, thermal, mechanical and chemical properties different from conventional materials. The microparticle surface film is a new type of material composed of a single layer or several layers of composite film coated on the surface of several different types of granular materials such as inorganic non-metallic, metal or organic polymers through a certain process. It can retain the main characteristics of the original component materials, and can obtain properties that the original components do not have through the composite effect. It can also make the properties of ...
